Swarm cases

receipt 15377: DGKI in dopamine neurons, braak

power
full sample +0.31 (p 0.218, n 18), 95% CI -0.19 to +0.68. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.29 (p 0.235, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.23 (p 0.365, n 18). could be the mix.
skeptic
leave-one-out range +0.23 to +0.47, sign flips 0; without severely affected donors +0.31 (p 0.218, n 18). fragile.
cell type
strongest in OPCs: +0.66 (p 0.0026, n 18) vs +0.31 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for DGKI in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
